ProMinent Beta BT4b - 13.2 Accuracy; 13.2.1 Standard Liquid End

13.2 Accuracy
13.2.1
Standard Liquid End
Specification Value Unit
Capacity range of the series -5 ... +10 % *
Reproducibility ±2 % **
* - at max.
stroke length and max. operating pressure for all mate‐
rial versions
** - at constant conditions and min. 30 % stroke length
13.2.2 Self-Bleeding Liquid End
As the self-bleeding liquid end is used with outgassing media and
when operating with air bubbles
, no dosing accuracy or reproduci‐
bility can be provided.
The recommended minimum stroke length with self-bleeding dosing
pumps is 50 %.
13.3 Viscosity
The liquid ends are suitable for the following viscosity ranges:
Version Range Unit
standard 0 ... 200 mPas
With valve springs 200 ... 500 mPas
Self-bleeding (SEK) 0 ... 50 mPas
HV (highly viscous) 500 ... 3000* mPas
* Only when the installation is correctly adjusted
